Description
Technical field
This utility model belongs to coal-burning power plant's minimum discharge technical field, is related to a kind of coal-burning power plant's minimum discharge device.
Background technology
As atmosphere polluting problem is increasingly serious in recent years, country and local government department have put into effect tightened up pollutant
Emission limit standard, it is desirable to which smoke dust discharge concentration is not higher than 5mg/m3, typically consider to arrange wet electrical dust precipitator dress after desulfurization
Put and particulate matter, acid mist and heavy metal etc. in flue gas are further removed, to meet the requirement of minimum discharge standard.
For conventional coal-burning power plant, chimney, cooling tower, desulfurizing tower and wet electrical dust precipitator are independently arranged, thus band
The problems such as coming big initial investment height, floor space, high energy consumption.By desulfurizing tower, wet electrical dust precipitator and smoke extractor are arranged
In indirect cool tower, the functions such as air cooling, desulfurization, dedusting, smoke evacuation are can achieve, with significant environmental benefit, while can economize on water, save
Can, save the area.
Occurred in that the arrangement that desulfurizing tower and wet electrical dust precipitator is arranged in indirect cool tower in domestic electrical construction of environmental protection
Form.
For part power plant, due to compact arrangement of equipment in indirect cool tower, wet electrical dust precipitator is caused to arrange in indirect cool tower
Difficulty, can only be arranged in wet electrical dust precipitator outside tower, floor space thus will be brought to increase, energy consumption is the problems such as increase.At present
In the four towers unification arrangement for having occurred, desulfurizing tower, wet electrical dust precipitator, flue, smoke extractor etc. are independent to be arranged, still deposits
Floor space is big, flue resistance big, high energy consumption the problems such as.
Utility model content
The purpose of this utility model is the shortcoming for overcoming above-mentioned prior art, there is provided a kind of coal-burning power plant's minimum discharge
Device, the device land area are little, and flue resistance is little, and energy consumption is low.
For reaching above-mentioned purpose, minimum discharge device in coal-burning power plant's described in the utility model includes indirect cool tower, Yi Jishe
The housing being placed in indirect cool tower, the desulfuration absorbing tower being fixed in housing, cleaner unit and smoke extractor, wherein, desulfuration absorbing tower,
Cleaner unit and smoke extractor are sequentially distributed from bottom to top, and the exhanst gas outlet of desulfuration absorbing tower is connected with the smoke inlet of cleaner unit
Logical, the exhanst gas outlet of cleaner unit is connected with the entrance of smoke extractor, and the outlet of smoke extractor is connected with the outlet of case top
Logical, housing erects the bottom for being fixed on indirect cool tower.
The cleaner unit is wet electrical dust precipitator.
The smoke inlet pipelines of desulfuration absorbing tower sequentially pass through the side of housing and the side wall of indirect cool tower reaches indirect cool tower
Outward.
The outer wall of housing is provided with some reinforcements being interspersed.
This utility model has the advantages that：
Minimum discharge device in this utility model coal-burning power plant includes indirect cool tower and the housing being arranged in indirect cool tower, consolidates
Desulfuration absorbing tower, cleaner unit and smoke extractor in the housing, the outlet of smoke extractor are connected with the outlet of case top,
Housing erects the bottom for being fixed on indirect cool tower, so as to desulfuration absorbing tower, cleaner unit and smoke extractor are fixedly connected, and then will be de-
Sulfur absorption tower, cleaner unit and smoke extractor are fixed in indirect cool tower, and flue gas is successively through desulfuration absorbing tower, cleaner unit and smoke evacuation dress
Put, then by indirect cool tower lifting flue gas, realize sulfur dioxide and the flue dust minimum discharge of flue gas, this utility model collection air cooling, de-
Sulfur, dedusting, smoke discharging function in one, while reaching water saving, energy-conservation and the purpose that saves the area.Space bit is made full use of simultaneously
Put, do not increase floor space newly, reduce engineering initial investment, cold between making power plant's layout more rationally attractive in appearance and further optimizing
The interior layout of tower, compared with conventional 600MW units, reduces and takes up an area about 650m2.In addition, this utility model cancels desulfurization absorbing
Flue between tower, cleaner unit and smoke extractor, reduces the resistance of flue gas system, reduces operation power consumption, with conventional 600MW units
Compare, reduce SR about 200Pa, reduce system power consumption about 153kW, solve about 350,000 yuan of operating cost in year.
Further, the outer wall of housing is provided with some reinforcements being interspersed, and housing is reinforced by reinforcement,
Avoid the work of desulfuration absorbing tower, cleaner unit and smoke extractor from rocking but housing is impaired, realize desulfuration absorbing tower, cleaner unit and row
The fixation of cigarette device.
